" tBe it-known that I,--J Mns F. CRAVEN, a

semisolid 'and- -Pasty in the county of Alleresident of Pittsburg ennsylvania, have 1n- The device is intended more particularly for putting up lubricants in the form of greases and discharging the same into grease cups" of machines, I for the purpose of enabling grease to be. supplied to bearings Without liability of dirt or grit entering the bearings with the grease, and also to prevent smearing orsoiling the hands of the workman or the machinery. The invention, however, is not limited to this particular use,

= but is adapted for putting up in a substandevice; Fig. 2

tially sealed condition any semi-solid or pasty substance such as soap, etc., and delivering the same from the container in any desire quantity; or quantities. 1

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

' Inthe accompanyingdrawing Figure l is a vertical section. through one form of the is a plan view of the same; and Figs. 3, 4, and .5 are vertical sections through modified forms of the device. .-,The receptacle or container may be of any desired size orshape, and may be built up or constructed in any; desired way. As shown in the drawings the receptacle is formed by a substantially cylindrical tube 1 which may be of sheet metal or other thin substance, and is shown as formed from paste or paper board. .-One end of this receptacle ispermanently closed by the head 2,

' whichas shown is composed of sheet metal crimped onto the end of'the paper tube.

T-he other end of the receptacle is provided closure or head in order to cap 3 secured to-the body of the receptacle by a threaded connection 4 wi h a sheet metal-ring 5 which is crimped onto the pasteboard body 1.- Any other suit- Specification of Letters Patent. 1 Application. filed September 20, 1910.

able closure for this end will answer the purpose.-

In the form shown in Figs. 1, 2, and 3 the outlet orifice is at 6 through the cap 3, said orifice leading to the discharge tube or spout 7 which in turn is closed by a cap 8 having a threaded or other suitable tight connectlon with said spout. In the receptacle 1 is a movable piston or follower 9 provided with a leather cup 10 or other suitable means providing a close fit in the receptacle. The piston or follower 9 may be either stamped u of sheet metal, as shown in Fig 1, or may lie a Wooden disk as shown at 9 in Figs. 3, 4, and 5, of any other suitable substance. In order to force the substance from the container the piston is moved longitudinally in the tube 1.

of the receptacle Various -means may be adopted for this purpose. As shown in the drawings the movement of the piston is eflected by connecting thereto a wire or wires, or other suitable flexible connectors, which pass'through openings in the opposite head of the recep-- tacle andare adapted to be wound upon a suitable rotating key or shaft. Figs. 1 and 2 show a single wire 12 secured centrally to a small hole in the cap 3 and then suitably secured to the key 13 which is provided with a turning handle 14. The attachment of the wire to the ke can -be readily effected by passing the end of the wire through a trans verse hole in the key. In this form the key is rotatable in a pair of bearings 15 soldered or otherwise suitably The cap at its center is provided; with a depression 16 to accommodate the coil of Wire woundon the key.

Fig. 3 shows a slight modification wherein a pair of wires 12 are secured tothe piston; each extending through an opening in the cap 3 and secured to the winding shaft13. In this form the turning handle 14; insteadof being integral with the winding shaft is pivoted thereto at 17 so that when not in use it hangs at the side of the rece tacle.

discharge and through the upper head'of the are held at one Q the body receptacle, where it is provided with the usual closure 8. The admission orifice 6 in the lower end of the discharge tube 7 is of smaller size than the interior diameter of said tube. The iston is shown connected to the winding sha or key. by means of a pair cf metal, ribs or flat wires 12". The handle :lr key v14. is detachable. from the winding aha-n13 bya threaded joint 20., In Fig. 5 the cap or closure 3. isprovided with the central discharge orifice 6* and with a comparatively large dischargespout "I centrally arranged on said cap. The winding shaft or key 13 passes through the spout 7 and the wire 12 is wound thereon inside of said spout. In'this form, the key and coil of wire" thereon are practically within the receptacle and are concealed. With all forms of the device the receptacle is filled with grease, soap or other pasty or semi-solid substance through the end which is closed by the removable cap 3. While be- 5 ing filled thepiston is in of the receptacle, and the ends of the wire receptacle. When filled the ends of t he wire or wires are passed through the hole or holes in the cap 3, and the cap is then screwed, crimped or otherwise secured onto of the receptacle. When a 'plurality'of wires or bands are used the cap with the .ends 'of thewire extending therethrough must first be turned backwardly to the same extent as it is necessary to turn it forwardly in order to screw the same onto the body of the receptacle, in order that the wires may direction so that when the cap is fully in place the wires will be practically without twist. A slight amount of twist, however, will do no particular harm. Inasmuch as it requires not to exceed one turn to screw the cap fully to place it is not difiicult to determine the amount of reverse twist to be given to the wires. The ends of the wire or wires are then passed throughthe holes in the win'dingshaft and the latter is given several turns to sharply bend the wire and hold the latter from accidentally pulling'out of the winding shaft. The receptacles are filled in this manner and hermetically closed or sealed at the factory, and. can then be conveyed to the place of use. To supply. the contained substance to the machine bearings, or for other purpose it is merely necessary to unscrew the small closure 8 and then slightly rotate the winding shaft or key 13, so as to Wind thereon the wire or wires and draw the piston or follower toward the discharge orifice. This forces the semi-solid or pasty substance from said orifice and through the discharge spout. Any desired quantity of material can be discharged in th s manner from the receptacle and when the required quantity is dischargedthe small closure 8 is again first be twisted in a reverse.-

The contents of the receptacle are always-contained in a tightly c not accumulate 'dirt, nor, as-for instance with the caseof butter, willodors from substances which are storedin the same room 'or vicinity. The device described is adapted particularly for containing and discharging substances like lubricating greases and soaps which are semi-solid rather than pasty,v
